Personality and abilities
Yunobo is very timid and easily frightened, frequently cowering in fear when confronted by monsters. However, he is quite friendly, and quickly offers Link his assistance in his quest to free Vah Rudania. He is also seen waving gleefully when he glimpses the spirit of Daruk atop Vah Rudania as the latter prepares to fire upon Hyrule Castle.
Yunobo, as a descendant of the champion Daruk, can utilize his ancestor's special ability, Daruk's Protection, seemingly with as much skill as Daruk himself. This skill greatly helps Link during his mission, as it allows Yunobo to protect himself from enemy attacks (including Vah Rudania's magma bombs) and use himself as a makeshift cannonball against the corrupted Divine Beast during the trek up Death Mountain.
